Abstract

Organic polyisocyanates characterized by allopho­ nate linkages are prepared by reacting an organic polyisocy­ anate with a mono- or polyhydric compound in the presence of an organo metal catalyst. The catalyst is then deactivated using a compound such as an inorganic acid, organic acid, organic chloroformate or an organic acid chloride. The isocyanates are useful in preparing polyurethane foams.
